Oil-fired boilers include oil-fired water boilers, oil-fired hot water boilers, oil-fired heating boilers, oil-fired bath boilers, oil-fired 1ton steam boilers and so on. Oil-fired boilers are boilers fueled by light oil (such as diesel oil, kerosene), heavy oil, residual oil or crude oil. Oil-fired boiler, gas-fired boiler, electric heating boiler is more economical than electric heating boiler and more convenient to use than gas-fired boiler compared with vertical oil-fired hot-water boiler.
Oil-fired boiler maintenance methods "" A lot of companies because after the purchase of oil-fired boilers, Careless maintenance process, with the result that the useful life of oil-fired boiler is greatly reduced. So how should it be maintenance of the oil-fired boiler? The following article gives you a detailed analysis. After conducting oil furnace shut until the furnace cooled water to the boiler water below 70 ℃ exhausted, the internal completely remove the dirt, washed away, all manholes, hand holes, valves and other pipeline tight blockade, and with a blind plate and running boiler completely isolated. After all of the alkaline solution is added, and then injected into the soft water boiler, until the water coming out from the highest point till the boiler, the water supply valve is closed, note that the average mixing an alkaline solution inside the boiler. Stop oil-fired boiler more than a month, maintenance of law should be dry, wet maintenance shutdown method can be used the following month. To schedule the maintenance period Microflame oven, schedule the water cycle, the concentration of the alkaline solution throughout the same. Every five tests also take a basic solution, such as alkalinity less than 5-12mmol / 1 solution should be applied. Periodic inspection outage before the oil-fired boiler furnace, should be prepared to work the following three aspects: (1) review the registration technical dossier furnace boiler and boiler furnace usage understand. In order to fuel the transformation within the furnace boiler external inspection be aware, the general need to understand: the transformation of the electric furnace boiler design, manufacture, installation; boiler furnace revamping; boiler furnace use history and usage; boiler furnace water treatment case ; boiler performance and other rules and regulations. (2) Check before shutdown preparation. First, with the production schedule maintenance shutdown date, and then let the transformation of the normal furnace boiler shutdown program shutdown, but slowly disheartened. Injecting cooling method may be employed downcast water, replacing the water cooled furnace and the furnace into line ventilation cooling. When the boiler water temperature was reduced to 70 ~ 80 ℃, before drainage. Open all doors hole. When the door opened, to prevent warm water, steam jet man suddenly burns. Corresponding to the passage blocked pipe on the transformation test furnace boiler steam, water supply, sewage and other pipes and other run in the transformation of the electric furnace boiler. Blocked with shutter have sufficient strength to avoid being broken drum high pressure medium. To clear the blocking position is indicated. And other operational boiler furnace flue should be communicated reliably cut off. Also to clear the transformation of furnace soot and scale boiler by warm surface. (3) test preparation tools and lighting. In order to ensure the smooth entry inspection, the inspector should prepare the necessary equipment, tools, measuring tools and safe and reliable lighting devices.
Inside the Fangkuai boiler plant, there is a special corrugated furnace bladder production line, which can be processed according to the computer setting mode. At the same time, this is also a unique processing technology of Fangkuai Boiler. The cost of natural gas fuel alone exceeds 5 million yuan per year. The corrugated furnace liner fired by this production line can not only increase the heating surface of the boiler, but also alleviate the damage caused by the thermal expansion and contraction to the combustion chamber, and greatly extend the service life of the boiler.
Dry: six gas-fired boiler safety procedures (hot water + steam) stage, the purchase of gas-fired boiler more and more users, in many industries, such as oil exploration, hospital disinfection, chemical production, wine feed, and so on. But many users initial contact with a gas boiler told us how to get started quickly boiler operation is not clear. First, all personnel must be familiar with the operation of the boiler boiler performance and safety knowledge, certificates; this non-job employees Never operate. Duty personnel should strictly follow the regulations, do a good job operating records and shift recording, the security situation should shift equipment and run tests, carried out. When the shift to check the boiler is intact. Second, purchasing, installing, or before the initial operation of the boiler, the boiler and safety accessories must conduct a comprehensive inspection, inspection and determined within the validity period to start. Third, Kai furnace ready to check the gas pressure is within the normal range of values, not too high or too low; check whether normal pump Sheung Shui, if unusual you need to open the purge valve until the Sheung Shui so far. Open the door of each section Water Supply System (including Sheung Shui before and after the festival gates pumps and boilers); check the water level, the water level should be in the normal position, the water level gauge, a water color need to plug in the open position, to prevent false water level, if missing water can be manually Sheung; check valves on the pressure pipe, must be opened, the wind deflector must all flue opening; each knob inspection control cabinet are in their normal position; 1ton steam boiler check valve is in the normally closed state, heat water boiler circulating pump outlet valve should be turned off; check water softening equipment is operating correctly, soft indicators of compliance with national standards. Fourth, Kai furnace run time 1, steam boilers Open the power to start the burner; check manholes, hand holes around the flange and valve leaks will be tightened, if there is still leakage after tightening occurs, you need to immediately stop maintenance furnace; l when the air pressure 0.05 ~ 0.1MPa, replenishment, sewage, water supply systems and sewage screening test device while flushing water table; when the pressure was raised to 0.1 ~ 0.15MPa, rinsed trap gauge; pressure was raised to 0.3 MPa, the "fire load / small fire" knob to "fire" to strengthen the combustion; 2/3 when the air pressure was raised to the operating pressure, start warming air supply tube, slowly open the main steam valve, to avoid water hammer; out when the drain valve when steam is completely close it; after all drain valve closed, slowly open the main valve to open, and then half a turn; "burner control" knob to "Auto"; level adjustment: adjusting the water level (according to the load manually when to start and stop the pump), low load level should be slightly higher than the normal level, high load level should be slightly lower than the normal level; steam pressure adjustment: adjusting the combustion load in accordance with (manual adjustment fire / small fire) determines combustion conditions The flame color, smoke color determination condition atomisation air quantity and exhaust gas temperature observed concentration chimney, the best change in the combustion temperature to be adjusted according to the combustion. 2, start the circulation pump hot water boiler; startup burner; 15 minutes after start, "" fire load / small fire "spin-bit color button to" fire ";." Burner control "knob to" Auto "five, normal stop 1 furnace, hot water boilers' fire load / small fire "knob to" small fire "; off the burner; close the fuel supply valve; closing dampers; boiler after the temperature dropped to 50 ℃, the pump outlet valve closing cycle ; .2 circulation pump is stopped, the position of the steam boiler "fire load / small fire"; Close combustor; steam pressure drop when the sewage to 0.05-0.1MPA; closing the main steam valve; manual replenishment to the higher level; Close valve; Close supply valve combustion; closed dampers; six off the main power, an emergency shutdown, the steam boiler main steam valve closed; off the main power; 2, boiler water boiler inlet and outlet valve closed; opening the emergency valve and the emergency discharge replenishment valve; off the main power switch; notification superiors.Free Chat
